Low-enthalpy subgeothermal energy represents one of the most stable and environmentally friendly renewable energy sources for heating and cooling buildings. The efficiency of these systems largely depends on the geological and hydrogeological characteristics of the soil in which the geoprobes are installed in the case of the "soil-water" system or ...

The Ibarac tunnel was excavated as part of the Rožaje bypass project in Montenegro. Nearly half of the excavation was carried out in glaciofluvial sediments consisting of brown sandy clay with gravel and rock fragments. As the original design did not anticipate tunneling through such deposits, the subsequent adoption of overly optimistic geotechnic...

In this paper, the authors address the inspection of concrete structures using ground-penetrating radar (GPR) scanning technology. The main idea is focused on the inspection of a concrete structure for the purpose of detecting reinforcement or objects with a circular cross-section. The analysis includes both dry and wet concrete, as well as metalli...

Nature-like fish passes are complex hydraulic–ecological systems whose performance is often assessed through fragmented monitoring approaches. This paper proposes an integrated KPI-based framework for the evaluation and classification of fish pass functionality, combining biological, hydraulic, and operational indicators within a structured m...

This paper analyses the susceptibility of territory of municipality Čelinac to flash floods using the Flash Flood Potential Index (FFPI). All operations related to calculating the FFPI were conducted in a GIS environment. The research results showed that 38.42% of the territory belongs to the category of low susceptibility to flash floods. The cate...

In this paper, the control of the geometry of a bridge located in Kula, Serbia, was performed. This bridge bridges the Danube-Tisa-Danube canal and is a part of road 108 that runs from Bačka Topola to the Croatian border. In order to perform the geodetic control of the bridge's geometry, terrestrial laser scanning of the bridge was conducted, where...

The area of Niš, the third Serbian most populated city, has a dynamic topography. Located in a valley crossed by several rivers, surrounded by hills and plains, the rural settlements around the city, that were administratively integrated into it, are extremely diverse. The consequences of such variety are many, reflecting on residential bloc...

Geodesy and crustal deformations are closely related. On the one hand, geodetic techniques are used to estimate deformations contributing in this way to geology, seismology and geodynamics. On the other hand, deformations consist a major challenge in the maintenance of geodetic reference frames. In this work we use GNSS (Global Navigation Satellite...

The problem of circle’s centre determination by using geodetic data is related with influences of inevitable errors as a result of measurement process as well as with the issue of model’s influence itself. In this research the experiment was conducted with aim to find out the influence of measurements error and the influence of model fo...
